Low Recurrence Rate After Laparoscopic (TEP) and Open (Lichtenstein) Inguinal Hernia Repair A Randomized, Multicenter Trial With 5-Year Follow-Up

Forskningsoutput: TidskriftsbidragArtikel i vetenskaplig tidskrift


Objectives: To compare a laparoscopic (totally extraperitoneal patch (TEP)) and an open technique (Lichtenstein) for inguinal hernia repair regarding recurrence rate and possible risk factors for recurrence. Summary Background Data: Laparoscopic hernia repair has been introduced as an alternative to open repair. Short-term follow-tip suggests benefits for those patients operated with a laparoscopic approach compared with open techniques; ie, less postoperative pain and a shorter convalescence period. Long-term results, however, arc less well known. Methods: The study was conducted as a Multicenter randomized trial with a 5-year follow-up. A total of 1512 men aged 30 to 70 years, with a primary unilateral inguinal hernia, were randomized to either TEP or Lichtenstein repair. Results: Overall, 665 patients in the TEP group and 705 patients in the Lichtenstein group were evaluable. The cumulative recurrence rate was 3.5% in the TEP group and 1.2% in the Lichtenstein group (P = 0.0081). Test For heterogeneity revealed significant differences between individual Surgeons. The exclusion of 1 surgeon, who was responsible for 33% (7 of 21) of all recurrences in the TEP group, lowered the cumulative recurrence rate to 2.4% in this group, which was not statistically different front that of the Lichtenstein group. Conclusions: The recurrence rate for both TEP and Lichtenstein repair was low. A higher cumulative recurrence rate in the TEP group was seen at 5 years. Further analysis revealed that this could be attributable to incorrect surgical technique.
